Description

Technical Field

[0001] This utility model relates to the technical field of blast furnace taphole plugging equipment, and in particular to an anti-sticking taphole mud clamp. Background Technology

[0002] In the blast furnace ironmaking process of ironmaking plants, the taphole blocking operation requires the use of a mud gun machine to press the taphole mud into the taphole to achieve the purpose of blocking the taphole. The traditional method of manually loading the taphole mud into the mud gun machine has problems such as high labor intensity and high temperature and dust environment that harms the health of operators. Therefore, mechanized taphole mud clamps have become the mainstream solution.

[0003] Existing shotcrete grippers generally use a rigid conical bar gripping structure to grasp shotcrete, but this has significant drawbacks in practical applications: because the gripper is a rigid structure, when the conical bar is inserted into shotcrete with a certain hardness, the shotcrete reaction force acts directly on the gripper, which can easily cause the conical bar to deform or even damage the gripper, especially in high-frequency operations, seriously affecting the service life of the equipment; at the same time, the positioning of the shotcrete by the gripper depends on the precise landing point, but if the gripper is not in the center of the shotcrete or there is a local hardness difference in the shotcrete, the force on the two conical bars will be uneven, generating a lateral offset force, which will further aggravate the damage to the gripper structure; and the shotcrete reaction force acts directly on the robotic arm through the gripper, which can also cause the robotic arm to overload and stop suddenly. In addition, during the production and transportation of taphole clay, it is easy for the clay to vary in size and shape. Traditional clamps are difficult to adapt to various shapes, and the clay may fall off during handling due to insufficient penetration depth of the cone or failure to penetrate special shaped parts. More importantly, existing clamps lack an automatic release mechanism when the clay is deployed. The clay is easy to soften and stick to the clamp due to friction or high temperature, requiring manual intervention. This not only reduces work efficiency but may also cause safety hazards.

[0004] Therefore, in response to the aforementioned multiple technical bottlenecks, there is an urgent need for a clay clamp with buffering, adaptive adjustment and anti-adhesion functions. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-adhesion clay clamp. By setting up a buffer component, an offset component and a clay holding component, it solves the problems of easy damage to the rigid structure, uneven force, unstable gripping and clay adhesion of the existing clay clamp. It achieves the effects of buffering and shock absorption, adaptive offset calibration, stable gripping of clay of various shapes and prevention of adhesion during delivery.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0007] A clay clamp for preventing adhesion includes a gripping assembly, a clay-holding assembly on the inner side of the gripping assembly, a buffer assembly on the top of the gripping assembly, and an offset assembly on the top of the buffer assembly. The clay-holding assembly is used to hold and compress clay of varying shapes. When the clay is being placed, the clay-holding assembly pushes the clay forward, displacing it from the gripping assembly to prevent adhesion. The buffer assembly provides a vertical movement buffer distance, and the offset assembly provides a horizontal offset buffer distance.

[0008] Preferably, the gripping assembly includes two symmetrically arranged independent gripping cylinders, and the two gripping cylinders are respectively connected to the spike through corresponding connecting rods to drive the spike to grip the mud.

[0009] Preferably, the cone is a rigid structure used to insert into the clay for fixing, and the clay is prevented from falling off due to its irregular shape by the clamping action of the clay-holding assembly.

[0010] Preferably, the mud-holding assembly includes a mud-holding cylinder and a gripper. The mud-holding cylinder is fixedly installed on the inner wall of the gripper assembly. The gripper is rigidly connected to a piston rod, and the piston rod drives the gripper to move along the inner side of the gripper assembly to ensure that the irregular surface of the mud fits tightly with the spike.

[0011] Preferably, the buffer assembly includes a buffer, a buffer cylinder, and a buffer plate. The buffer plate is connected to the top of the gripper assembly. One end of the buffer cylinder is connected to the buffer plate, and the other end is connected to the offset assembly. The buffer is disposed inside the buffer cylinder to provide vertical movement buffering.

[0012] Preferably, the buffer plate of the buffer assembly is fixedly connected to the top of the gripping assembly by bolts, and the top of the buffer cylinder is fixedly connected to the bottom of the offset assembly.

[0013] Preferably, the offset component includes a T-shaped plate and a damping buffer. The T-shaped plate includes a transverse groove and a longitudinal slider. The longitudinal slider is connected to the top of the buffer component. The transverse groove achieves left and right offset buffering through the damping buffer.

[0014] Preferably, the damping buffer of the offset component is disposed in the transverse groove of the T-shaped plate to absorb the transverse impact force generated by the clamp due to the irregular shape of the clay or the asymmetry of the gripping point.

[0015] According to the specific embodiments provided by this utility model, the following technical effects are disclosed:

[0016] (1) This utility model sets a mud-holding component inside the gripper assembly, uses two independent gripper cylinders to drive the cone spike, and drives the gripper to hold and press the mud by the mud-holding cylinder. This allows the gripper to adaptively adjust the gripping force according to the shape of the mud. The dual action of cone spike insertion and holding and pressing achieves stable gripping. At the same time, the mud-holding component automatically pushes out the mud when it is deployed. This solves the risk of falling and sticking caused by the irregular shape of the mud in traditional grippers, and improves the gripping reliability and operation efficiency.

[0017] (2) By setting a buffer assembly consisting of a buffer, a buffer cylinder and a buffer plate on the top of the gripper assembly, this utility model provides a buffer amount for up and down movement when the gripper contacts the mud, transforming rigid collision into an elastic buffer process, effectively absorbing the impact force of the mud on the spike, avoiding the spike bending or clamp structure damage caused by excessive instantaneous impact force, as well as the overload and emergency stop of the robotic arm, thus extending the service life of the core components of the gripper from the perspective of mechanical buffer.

[0018] (3) This utility model provides a displacement component consisting of a T-plate and a damping buffer on the top of the buffer component. The T-plate’s transverse groove and longitudinal slider structure provide a space for movement compensation for the transverse force generated by the irregular shape of the clay or the asymmetry of the gripping point during the gripping process. The damping buffer absorbs the transverse impact energy, so that the clamp can adaptively adjust the offset angle, balance the force difference on both sides, reduce the stress concentration of the structure, and improve the clamp’s impact resistance and stability under complex working conditions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1 Wherever Figure 3 This utility model provides an anti-adhesion clay clamp, including a gripping assembly 1. The gripping assembly 1 serves as the basic load-bearing structure of the clamp, with a clay-holding assembly 2 installed on its inner side, and a buffer assembly 4 and an offset assembly 3 connected sequentially to its top. The gripping assembly 1 includes independent gripping cylinders 5 symmetrically distributed on both sides. The two cylinders are hinged to a conical spike 7 via a connecting rod 8, forming a linkage structure: when the piston rod of the gripping cylinder 5 extends or retracts, it drives the conical spike 7 to move horizontally through the connecting rod 8, thereby realizing the gripping or releasing action of the clay.

[0029] The mud-holding assembly 2 includes a mud-holding cylinder 6 and a gripper 13. The mud-holding cylinder 6 is fixed to the inner wall of the gripping assembly 1, and its piston rod is rigidly connected to the gripper 13, which can drive the gripper 13 to slide laterally along the guide rail inside the gripping assembly 1. After the gripping cylinder 5 completes the initial insertion of the cone 7 into the mud, the mud-holding cylinder 6 is activated, pushing the gripper 13 to apply gripping pressure to the surface of the mud, so that the cone 7 is tightly attached to the irregular surface of the mud. When it is necessary to release the mud, the gripping cylinder 5 moves in the opposite direction to disengage the cone 7 from the surface of the mud, and the gripper 13 continues to push the mud forward to avoid adhesion.

[0030] The buffer assembly 4 consists of a buffer plate 12, a buffer cylinder 11, and a buffer 9. The buffer plate 12 is fixed to the top of the gripping assembly 1 by bolts. The bottom end of the buffer cylinder 11 is bolted to the buffer plate 12, and the top end is fixed to the bottom surface of the offset assembly 3. The buffer 9 is set inside the buffer cylinder 11 and is usually a spring or hydraulic damping structure. When the clamp contacts the mud, the gripping assembly 1 can move slightly in the vertical direction through the buffer cylinder 11. The buffer 9 absorbs the impact energy and avoids rigid collisions that could cause the spike 7 to bend or the clamp structure to be damaged.

[0031] The offset component 3 adopts a T-shaped plate 10 structure, with its longitudinal slider fixedly connected to the top of the buffer component 4. A damping buffer 9 is embedded in the transverse groove, allowing the longitudinal slider to slide left and right in the transverse groove. When the two conical spikes 7 are subjected to uneven force due to the irregular shape of the clay or the offset of the gripping point, the entire fixture can offset the transverse force through the sliding displacement of the transverse groove. The damping buffer 9 absorbs the impact energy simultaneously to achieve force balance.

[0032] Working principle: In use, the clay clamp is moved above the clay to be gripped by a robotic arm. The two independent gripping cylinders 5 of the gripping assembly 1 synchronously drive the conical spike 7 downward to insert into the clay, completing the initial positioning. Then, the clay-holding cylinder 6 is activated, pushing the gripper 13 to move up and down along the inner side of the gripping assembly 1, pressing the clay surface from above. Through the dual action of the conical spike 7 insertion and the pressing, the irregularly shaped clay is firmly clamped. During the insertion of the conical spike 7, if an impact force is generated due to uneven clay hardness or clamp placement deviation, the buffer cylinder 11 and the buffer 9 of the buffer assembly 4 absorb the impact energy by moving up and down to buffer the impact, preventing damage to the conical spike 7 and the clamp. If a lateral offset force is generated, the T-shaped plate 10 of the offset assembly 3, through the cooperation of the lateral sliding groove and the damping buffer 9, allows the clamp to adaptively offset, balancing the forces on both sides. When the clamp moves to the mud gunner's placement position, the gripping cylinder 5 reverses its action—the gripping cylinder 5 releases the cone 7, and the mud-holding cylinder 6 pushes the gripper 13 to push the mud gunner out from the inside of the clamp, achieving non-sticky placement and completing the entire operation process.

[0033] Therefore, by adopting the above-mentioned anti-adhesion clay clamp, and by setting up a buffer component, an offset component, and a clay-holding component, the problems of easy damage to the rigid structure, uneven force, unstable gripping, and clay adhesion of the existing clay clamp are solved. It achieves the effects of buffering and shock absorption, adaptive offset calibration, stable gripping of clay of various shapes, and prevention of adhesion during deployment.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
